C++ Using in Array Pro

Multidimensional Array

#include 

#include

using namespace std;

void printarray(const int[][3], int);

int main() 

{

   int myarray[][3] = {{8, 2, 4}, {7, 5, 2}};

   printarray(myarray, 2);

   return 0;

}

void printarray(const int array[][3], int rows) 

{

   for (int i = 0; i < rows; ++i) 

    {

      for (int j = 0; j < 3; ++j) 

     {

         cout << array[i][j] << " ";

      }

      cout << endl;

   }

}

Multi-Dimensional Array

#include 

#include

using namespace std;

int main() 

{

   char msg[256]; 

   cout << "Enter a message (with space)" << endl;

   cin.getline(msg, 256);  

   cout << msg << endl;

    for (int i = 0; msg[i] != '\0'; ++i) 

     {

      cout << msg[i];

   }

   cout << endl;

   cout << "Enter a word (without space)" << endl;

   cin >> msg;

   cout << msg << endl;

   for (int i = 0; msg[i] != '\0'; ++i) 

   {

      cout << msg[i];

   }

   cout << endl;

   return 0;

}

Increment Each Element of an Array

#include 

#include

using namespace std;

void inc(int array[], int size);

void print(int array[], int size);

int main() 

{

   int a1[] = {8, 4, 5, 3, 2};

   print(a1, 5);   

   inc(a1, 5);     

   print(a1, 5);   

}

void inc(int array[], int size)

 {  

   for (int i = 0; i < size; ++i) 

   {

      array[i]++;  

   }

}

void print(int array[], int size) 

{

   cout << "{";

   for (int i = 0; i < size; ++i) 

    {

      cout << array[i];

      if (i < size - 1) 

      {

         cout << ",";

      }

   }

   cout << "}" << endl;

}

Search an Array using Linear Search

#include 

#include

using namespace std;

int linearsearch(const int a[], int size, int key);

int main() 

{

   const int size = 8;

   int a1[size] = {8, 4, 5, 3, 2, 9, 4, 1};

   cout << linearsearch(a1, size, 8) << endl;  

   cout << linearsearch(a1, size, 4) << endl;  

   cout << linearsearch(a1, size, 99) << endl; 

}

 int linearsearch(const int a[], int size, int key) 

 {

   for (int i = 0; i < size; ++i) 

   {

      if (a[i] == key) return i;

   }

   return size;

}

Functions and Arrays

#include 

#include

using namespace std;

int sum(int array[], int size);    

void print(int array[], int size);

int main() 

{

   int a1[] = {8, 4, 5, 3, 2};

   print(a1, 5);   

   cout << "sum is " << sum(a1, 5) << endl;  

}

int sum(int array[], int size) 

{

   int sum = 0;

   for (int i = 0; i < size; ++i) 

  {

      sum += array[i];

   }

   return sum;

}

void print(int array[], int size) 

{

   cout << "{";

   for (int i = 0; i < size; ++i) 

    {

      cout << array[i];

      if (i < size - 1) 

      {

         cout << ",";

      }

   }

   cout << "}" << endl;
